SERVICE INFORMATION
If a CVT appears to have oil seepage or a leak on the transmission, follow the steps below to assist in a correct
diagnosis.
1. Thoroughly clean off the area of the suspected leak.
2. Install one (1) fluid ounce of J-52990 Fluorescent Oil Dye* into the CVT.
3. Drive the vehicle for a minimum of 10 minutes (to ensure proper diagnosis).
4. Inspect the area with the lamp from the J-43926 A/C Dye Kit.*
 If a fluorescent oil trace/leak is not found, the stain is likely:

corrosion protection chemicals sprayed on the transmission,
and/or

lubricants, which are sometimes used to ease the assembly process.
NOTE: The chemicals/lubricants may cause dust to accumulate (gather) on the transmission and have
the appearance of an oil leak. Corrective action is not required should this occur.
 If a fluorescent oil trace/leak is found:

Repair using standard warranty procedures.
*These tools were made Essential in 2001 (J-52990) and 1999 (J-43926). To order additional supplies, call
